Spi 19-214-6 Class Zz Minus Plug Pin Gage 0.2140 Inch

Product Description

The SPI 19-214-6 is a Class ZZ minus plug pin gage used to verify bore and hole diameters to a nominal size of 0.2140 inches. Built from steel, this gage provides a minus tolerance of 0.0002 inches, keeping the gage undersized relative to the nominal dimension as required by Class ZZ go/no-go inspection standards. Machinists, tool-and-die makers, and quality control technicians use pin gages like this one to confirm that drilled, reamed, or bored features fall within specified tolerances before parts move to the next stage of production or assembly.

This gage is suited for production floor inspection, incoming quality checks, and toolroom verification work. It is appropriate for use on ferrous and non-ferrous workpieces wherever a 0.2140-inch nominal hole diameter must be confirmed. The steel construction holds up well under repeated insertion cycles in typical shop environments. Individual pin gages of this type are commonly used as part of a complete pin gage set or as a standalone replacement when a single size is needed.

Key Features

• Class ZZ minus tolerance gage — undersized by 0.0002 inches relative to nominal for go-gage applications
• 0.2140-inch nominal measurement diameter in steel construction
• Tight tolerance of 0.0002 inches supports reliable pass/fail dimensional inspection
• Compact and lightweight at 0.2 pounds — easy to handle during high-volume inspection tasks
• Single-piece packaging for direct replacement of a worn or lost gage in an existing set

Compatibility

Designed as an OEM-style replacement or standalone Class ZZ minus plug pin gage for use in any standard pin gage handle or holder accepting 0.2140-inch diameter pins.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Before use, inspect the gage surface for burrs, nicks, or wear that could affect measurement accuracy. Always clean the gage and the workpiece bore before insertion to avoid false readings or surface damage. Store the gage in a protective case or holder when not in use to maintain calibration integrity.
